South African bowler Dale Steyn has emerged as an injury doubt for Wednesday's ICC Champions Trophy semi-final against England at The Oval.

The 29-year-old was forced to miss two of the Proteas' three Group B matches with a side strain.

"He's had quite a lot of cricket, of late, with the IPL," team manager Dr Mohammed Moosajee told Sky Sports News. "He's one of our marquee players who plays all forms of the game, so the challenge with Dale is always to manage him."

Steyn took two wickets during his side's abandoned encounter with the West Indies in Cardiff on Friday.
